To @ZZ 'whom t may concern:

Be it known that I,l Tinus S. FAnNswonrn, a citizen of the United States, yresiding at San Francisco,l in the county of San Francisco and State of California, have invented certain new and useful Improve.- inents in Indiening-Registers for Locks, of which the following' is a description.

My invention belongs to that general class of devices known as locks, and more par-` ticularly to a lock provided with means for automatically registering and indicating the operation of the same. It is particularly adapted to coin controlled locks for regi-storing' the successive operations of the same, and consequently indicating' the total number oi' coins deposited. Asl shown, it is especially desirable for use in connection with the coin controlled and key actuated lock shown in my U. S. Letters Patent. No. 1,076,822, granted October QS, 1913, in which device thelatch bolt is prevented from being' operated. until the deposit of a proper token, and which is so constructed as to admit ot the key being .vithdrawi'i or thrown to locking; position only on the deposit of a proper coin or token. The use of the device herein described, however, is not limited to devices ot' that particular type, as the same may be applied to practically any lock, whether it be a key or combination. For the purpose ot' making the present invention clear, I

shall describe it as appli-ed to the type of lock illustrated in my pending application above mentioned and partially illustrated herein. 1

The invention has among,` its objects the production of a device of the -kind described that is simple and compact, attractive, et-

iicient, durable,l accurate, and satisfactory, Y.

that may be applied to locks already installed, and that cannotbe easily tampered with or manipulated to fraudulently change the reading' of the same. y

To this end my invention consists in the novel construction. arrangement and combination ot parts herein shown, and4 described, and more particularly pointed out.

in the claims. In the drawings, wherein like reference characters indicatie like or corresponding parts,

Fig', l2 is a sectional view taken substantially on line l2, 12 of Fig. 11.v l v As before mentioned, I `have illustrated in the drawings a form ot lock to which the registering device is particularly applicable and desirable. This device is not, shown complete in all details,` thejunderstanding of the complete lockbeing had by reference to my patent' mentioned.. The lock shown comprises a vplate l, which is secured to. a part 2 ot the door trame in proximity to the door It is immaterial whether the lock be 'placed upon the `door or upon the.

door trame, except in coin orv token` controiled locks it is morel convenient to place them upon the trame` so that the coin chutes v may be simplified in construction, particularly where a common till for receiving the tokens 1s employed. The lock shown is controlled by a key d, the well known pin lock( type of lock beingv illustrated, which is provided with a key cylinder 5, which extendsiutothe tub ular 'casing 9, l0 (seeFig. 4.) The ylock is provided with a suitable coin chute (not shown). 4 which the tokens may particular device embodying my improve-- andan opening 6, through be inserted. In this ments, the key Ll. is maintained and locked in the cylinder 5, and cannot be withdrawn or the latch bolt thrown to operative position until a token, such as a coin, is droppediin the slot 6. rEhe key may then be turned to lock the door and then be Withdrawn. As the key, however, is thrown to locking position, the registering mechanism hereafter described, registers and indicates the same through the opening 7 in the registering mechanism casing 8. lvl/*hen it is desired to unlock the door 3, the key is inserted and the latch bolt thrown to unlocking position, depositing the coin in the till, and at the same time the key is locked so that it cannot be again Withdrawn Without depositing another token.. The registering mechanism is so arranged ythat it will only register When the latch bolt is operatively actuated, that is, only when a coin is deposited. By this means the number of tokens depositedin the till may be easily checked. Locks of this type are particularly adapted for package checking lockers for use in public places, in which one may place an article desired to be checked, deposit the required token, lock the locker, taking the key check, that is, the key is the check. When ready to claim the article checked, the key is inserted and the locker unlocked, and at the same time the key is again locked in the lock until another token is deposited.

As most clearly shown in Figs. l and 7, 12 is the latch bolt, which is arranged to be actuated by a linger or part 11, carried by the rotatable cylinder 5. The latch bolt is carried by the support 17, and by the flanged side 16 of the lock plate 1, or in an equivalent manner. l have not considered it necessary to illustrate in detail the complete locking mechanism. i-rranged on the locking cylinder 5 is a suitable rockable or partially rotatable member 18, Which is connected by screws 24, or the equivalent (see Fig. 3) passing through slots 23 to the coin controlling mechanism (not shown in detail). Arranged on the member 18 is a rockable or partially rotatable plate 19, which is preferably flanged as at 20 to provide a collar, and provided with a tongue 21, which engages a pin 22 secured to the plate 1. Mounted on the plate 19 is a plate 25 having an extension 26, formed with a lug or flange 27, and provided with a Vpin 28. Mounted over the plate 25 is a suitable Washer 30, and `over this is mounted a dial member 31 (see Figs. 4 and 9.) The dial member 31 is provided with teeth, or that is With shoulders 32 about its circumference, one shoulder 33 being greater or deeper than the others. Arranged neXt to dial 31 is a washer 34, and over this is arranged a dial member 35, which is notched as at 36, so as to clearly show the characters on the dial 31, and form teeth for the pavvl for actuating the same. The flange 20 on plate 19 forms a stationary bearing for the dial. members.

rllhe lug or flange 27 on the extension 26 oit' the plate 25 extends down into a: notch neaaeae or recess in the edge of the plate 18, and is adapted to cooperate with either of the faces 18 or 182, as Will be more clearly explained in the operation of the device. @n the pin 28 is arranged a paivl 37 (see Fig. 5) which is provided Withl the tip or end 39 formed to engage with the shoulders 32 on the dial 31, and With an cnd 41 arranged to engage with the shoulders on the dial 35. 1t is also formed With a part 40, which is substantially the same thickness as the Washer 341, and which extends between the tivo dials, and guides the pavvl. lt Will be noted by referring to the iigure above referred to, that the end at 39 on the pawl extends slightly beyond the lower tace ot the end at al. rEhe end at 4&1 doesfnot engage the shoulders on the dial 35 and actuate the same at every movement of the pawl, but only after each complete rotation or the dial member 31. Each. time that the shoulder 33 is engaged by the end 39 of the pawhthe pavvl drops into the nick a suiiicient distance to permit the end l1 to engage with one oit the shoulders on the dial 35, so that the dial 35 is at tiat time moved suicientlv to bring the next or succeeding characters betere the opening 7 in the casing 8. rllhe paiv'l is normally maintained in operative position by a springl 38, or its equivalents for the purpose.

is the plate 25 is rocked by the engagement of the tace 18, When the cylinder 5 is moved by the key, the pavvl 37 is moved to engage a nen7 tooth on the dial 31. lV hen the key is turned to lock the door, or in the opposite direction, the shoulder 182, engaging With the extension or lug 27, moves the plate 25 and carries the paivl and dial to advance one character. lt will be noted that a certain initial movement is permitted of the key and cylinder betorethe shoulders 182 or 18 engage with the lug 27. rhis is lost motion, but it permits more characters to be placed on the dial, since the dial is not advanced as much as would be the case it the plate 25 ivas secured to the part 18, or what is the same thing, the paivl carried by the part 18. Y

The dials are prevented from moving tor- Ward When the paivl is moved to take a new bite, or that is. engage a new tooth on the dials, by the resilient pavvl or locking member 42. This member. asinost clearly shown in Figs. 3 and 7, ismaintained in position by the pin 22 and its eXtended'end 4t2', and is provided with the tivo faces 122 and 122, arranged to bear against the edges ot the dial members. 4The part 412i (see Fig. 7 bears against the edge of the plate and acts substantially as a friction brake, so that it does not move untilengaged by one or the other of the faces 18 or 182 with the lug 27. lhe casing 8 may be secured to the plate 1 1n any desired manner, screws or'boltsa being shown ttor purpose'. The opening` 7 is also preferably covered with glass or the like to prevent tamperingwith the dials through the opening. y

In operation, assuming that the parts are substantially as shown in Figs. 1, 2 and 8, when the key l is turned clockwiser so asV to throw the bolt 12, it being understood tlfiat a coin has been deposited in the slot 6., so that the key may be turned, the plate 18 is moved by the key so that the tace 182 engages the lug 2T and moves the plate 25 and extension 26, carrying the pawl 37, and this moves the dial 31, to bring a new character at the opening 7. The key may then be withdrawn from the lock. illhenthe key is re-inserted and turned to unlock the device or return the latch bolt to the position shown, the plate `and extension 26 is moved when the face 1S ot' the member 1S comes 1n contact with the lugv 27, moving the pawl 37 where it will engage a new shoulder 32 when the ke is ao'ain thrown to the lock-- ing position. In the particular coin controlled lock shown, the coin having been previously registered' is at this time released and dropped into the till. l/lhenever the dial 31 is rotated to bring the shoulder where it is engaged by the pawl tooth 39, the pawl 3T drops sui'liciently to allow the tooth 41 to engage with the dial 35, so that as soon as the key is turned, that dial is moved one character. The same is repeated when the dial 31 has again made a complete rotation. TWhile 1 have shown but two dials, it is, of course, obvious that there may be any number desired, and they may be connected to Vcarry one from the other, similar to the carrying between the two dials de` scribed, or in any equivalent manner. Grdinarily, however, two dials are suficient for the purpose, at least for illustrating the invention.

'The construction shown in Figs. 10, 11 and 12 is slightly different, but in operation the results are the same. Referring to these figures, 1 represents the plate provided with the coin slot (i, the key cylinder 5, and key Ll,

which cooperate with the lock cylinder casing 9. InA this device the casing -S, which is provided with a cover i9, is movable with the key and cylinder, that is, it rocks with the key cylinder 5. As shown, the casing part i8 is formed with a part 50, which is ksuitably connected with the coin controlled The casing 1s secured to thev mechanism. cover 49, which is secured to the cylinder 5. Arranged within the casing is a plate 52, which is provided with a` pin 57. Arranged adjacent the plate is a ratchet wheel which is suitably connected to a dial member 53, bearing suitable characters upon its face.

A. cooperating dial is provided with a` ratchet wheel 56 at the back, and' with Hcha-racters upon its face. Carried by the pin 5T is a pawl or pawls 58, which are provided with parts 60 and 61, arranged to engage the ratchet gear 56 and 5i respectively.. 1nthisk construction, the outer dial 55 Vmakes one complete rotation for each time the inner dial moves one'ch-aracter, the carrying being similia-r to the other constructiomthat is, by providing a somewhat deeper tooth or shoulder 56. (See Fig. 11.) The casing, when the key is turned in one direction or the other, contacts with the extension 52, operating" the pawl. Assuming that the parts are as shown in 1F ig. 11, when the key is turned clockwise, the casing engages with the face 52 of the extension 52, causing the pawl to move the dial 55 one character. lhen the key is turned in the opposite direction, the pawlis brought to a position to engage a new tooth, the casing engaging the tace 522 of the extension 52. The dials are prevented from moving backward by the resilient member 68, which extends over the pin 62, as shown at Fig. 11, and is arranged to engage with the member 51 and act as a brake, as in the other construction. rhere may be two openings in the cover-if desired so that the' dialsniay be read regardless of the position of the casing. l

As was previously mentioned, the register-- ing device is applicable for any type of lock, particularly a lock in which a part may be rocked, as is the cylinder 5. It may be usedv with or without the coin or token cmitrolling` mechanism, but is in most cases not required or desired where such mechanisms are not employed. It will be noted that the characters on the dials are inthe form of letters rather than numerals, although the numerals, or the equivalent, may be used it' so desired. The advantage of letters is that the public reading the dials cannot determine the amount deposited in the till, so that the temptation of robbing the till is done away with. The letters may also be arranged in different ways on dilerent registers, and a record of the register kept at the oiilice, sov that even an employee cannot determine the reading ot 'the registers without having access ntio the cards or records. This enables the auditor to secretly check the accounts ot the llessee oic the devices,y or the one having charge of the same. lt might also 'be mentioned that in connection with the registering devices,l means may be employed to cooperate therewith andrecord upon paper or the like the operations of the devices. This 1s merely suggested, and is not illustrated.r 1n the'two formsoil device illustrated.r the dials are -movable relative aptixed indicating point, to-wit, the opening through which the dialsA are seen. i An obvious ialternate construction would be a fixed dial and one or more movable indicating points or pointers. f

Having thus described my invention, it is obvious. that various immaterial modifications may be made in the same without departing from the spirit of my invention; hence l do not wish to be understood as limiting myself to the exact form, construction, arrangement or combination of parts herein shown and described, or uses mentioned.
